Well, "hardware reset" did work. As long as battery is connected, i could not resolve this problem. To solve it, remove "positive" cable (not a single tool needed) and put it back in place. Only thing which is lost is current date/time in lcd display.

Hi, my wife has also C3 1.6i from 2003. When i started engine it had similar symptoms as you seems to be having. Speedo meter doesn't show anything. Also a bunch of lights stay on in display. When i turn radio on, i can hear this sharp beep signal every 5 second or so. Otherwise car seems to be working but it is a bit hard to at least drive according to speed limit as i can not see any readings. Also, it does not help if i turn engine off and then back on. I also removed key from lock and put back on. It is also a bit weird that meter lights seem to stay on forever when this problem first occured. I have to try removing main battery and put it back on. I let you know my outcome.
